How do you write an equation in slope intercept form for (-8.5,6.75), (3.33,-9.75)

Misha Larkins [42]

M = y2 - y1 / x2 - x1
= - 9.75 - 6.75 / 3.33 - ( -8.5 )
= - 16.5 / 11.83

=> y= - 16.5 / 11.83x +b
6.75 = - 16.5 / 11.83 ( -8.5) +b
6.75 = 11.86 +b
=> b = - 5.11

Answer : y= - 16.5 / 11.83x - 5.11

Elina [12.6K]

Answer:

Step-by-step explanation:

The graph shows two function:

function f(x) is increasing exponential function of the form $f(x)=a^x$ passing through the point $(1,\frac{9}{2}).$ So, $f(1)=\frac{9}{2}\Rightarrow a^1=a=\frac{9}{2}$ and function f(x) has the expression $f(x)=(\frac{9}{2})^x;$

function g(x) is decreasing exponential function of the form $g(x)=b^x$ passing through the point $(-1,\frac{9}{2}).$ So, $g(-1)=\frac{9}{2}\Rightarrow b^{-1}=\frac{1}{b}=\frac{9}{2},$ so $b=\frac{2}{9}$ and function g(x) has the expression $g(x)=(\frac{2}{9})^x.$

Hence, option A is true.

Why can the value of the variable a in the expression a + 2 be any number?

Bas_tet [7]

Answer:

(a) Because the expression is not an equation

(b) Because the expression is an equation

Step-by-step explanation:

Solving (a): a + 2

The above expression can assume any value for a because it is not an equation.

Take for instance:

a = 2;

$a + 2 \to 2 + 2 = 4$

$a =-4$

$a + 2 \to -4 + 2 = -2$

The reason for this is because the expression is not an equation

Solving (b): $b + 2 = 5$

The above expression can assume only value for b, and the value is:

$b + 2 = 5$

$b = 5-2$

$b =3$

This means that only $b =3$ will make the equation true.

The reason for this is because the expression is an equation

To determine a percent equal to a fraction, why should you write the fraction with a denominator of 100

Furkat [3]

Since a percent is out of 100 then writing a percent in fraction form would be whatever the percent is over 100. so if youre trying to figure out what 70 out of 250 is in percent for you would write it like this:

if you need help understanding this or it doesnt make sense message me!!!
